Different risk factors and prognosis for early and late intrahepatic recurrence after resection of hepatocellular carcinoma

Abstract

Early and late intrahepatic recurrences after resection of HCC were associated with different risk factors and prognostic factors. Early recurrences appear to arise mainly from intrahepatic metastases, whereas late recurrences are more likely to be multicentric in origin. The current study suggests that different strategies may be needed for the prevention and management of early and late recurrences. Further studies based on genetic analysis of clonal origins of tumors are required to clarify fully the mechanism of early and late recurrences after resection of HCC.
